.To all whom it may oortoern;

Be it known that LCHARLES J. HIRLIMANN,

a citizen of the United States, residing at` upon the market,necessitating frequent reg-- y newals, end thereby "\..lyonience andexpense. The ordinary dry battery upon the market is compose 'of zincond,\oafrbon elements'separated by an absorbent material which is impreated vyitix the active material, generall su furie acid, any

ordinary depolzmzer, suc as dioxid of manganese, being also incorporetedinto the cell to prevent the zinc element from becomingV coated Withhydrogen hobbies. Gwing; to the fact that the absorbent :notei riel,generally soivirclustg takesA up a. great deal of space and is wholl'yneutral in the electrc chemical actions of the cell, only a. very smallamount of active of exciting material oon be introduced therein, whichis goen oxheusted by use or eva. oz'atee by la se time. VSince the cellis o'rf inarily soale. up, it is not oonvegsient to renew .this activematerial, and egon if the interior of the cell were made acc esible ltwould take a considerafble time for the absorbent material within thecell to cook absorb the necessary amount of the On these accounts noattempt is ordmarily made to renew the 'active material 40 ofV dry cell,the battery being generally thrown awaywhen exhausted. a

` The. object of myrinvention is to provide' a Aform of constructionwhereby the active mal tetial "thin the cell may he'z'enewed froni u'pand .rea nt.
